The device has a hollow ring (3) firmly connected with a shaft (1) or a ring, where the hollow ring has a compression chamber (17) flexibly deformable by a fluid medium. The chamber is connected with a device for producing and controlling the fluid medium and has a radially arranged circular clamping surface (4) for fixing the shaft or the ring in a fixed counter surface (25). The chamber is formed of two symmetrically or asymmetrically arranged half rings (6, 7) and has a pressure channel. |
